SPECIFICATION forming part of Letters Patent No. 573,280, dated December 15, 1896. Application filed May 9, 1892. Serial No. 462,343. (No model.)

To (LU rt-71,0771 t may concern.' i

Be it known that We, JOHN T. MEATS and TRUMAN W. DEAN, of Taunton, county of Bristol, State of Massachusetts,have in ven ted` an Improvement in Spinnin g-M ules, of which the following description, in connection with the accompanying drawings,is a specification like letters and figures on the drawings representin g like parts.

This invention has forits object the improvement of mules used in the spinning of cotton or other fibrous material, and relates particularly, first, to those parts of the machine which draw the carriage in and out; second, to mechanism for changing the direction of action or movement of the carriage at the end of its drawing and spinning and of its winding movements; third, to the nosing mechanism or means for pointing the cop; fourth, to means for regulating the feed of the quadrant-scrcw- These and other features of ourinvention will be hereinafter more particularlydescribed, and pointed out in the claims at the end of this specification.

y Heretofore the functions of drawing' the carriage in and out have been performed by means of scrolls andropes or by racks and gearing. The objection to the former plan is that the ropes, owing to their elasticity and consequent tendency to stretch when much strain is put upon them, fail to cause the motion of the carriage to agree at all times with that of the rolls which deliver the yarn to be spun,such variations in motion causing either an undue stretching or a kin kin g of the yarn, as the case may be.

The chief objection to racks and gearing consists in their lackot' adaptability to the uniform acceleration and diminution of speed required in drawing the carriage quickly and certainly toward the beam. To overcome these difficulties and insure positive acceleration and diminution of speed of the carriage, we have devised a mule wherein the motion of `the carriage is effected by a scroll and a iiexible metallic connection which is wound thereon during the inward run of the carriage, said metallic" connection, herein shown as a chain or band, being joined at one end to said scroll and at its other end to a drum. This drum devised by us is operatively connected by suitable gearing, to be described, with and so as to rotate the shaft Whichimparts movement to the carriage, said shaft being commonly and hereinafter designated as the back shaft, the said shaft `in turn being joined by flexible metallic connections, preferably sprocket-chains, with the said carriage. By the employment of ilexible metallic connections the motion of the carriage is always positive in its relation to other parts of the mule. The mechanism for changing the direction of action, that is, for reversing the motion of the carriage at each end of the draw or stretch, so as to spin and wind alternately, has usually heretofore been arranged in such a manner that it did not permit of easy alteration or of delicate adjustinent to the various conditions under which the mule ought to Work on different kinds of yarn; and it is to overcome this dif- `iiculty that another portion or part of our `invention has been devised.

The means devised b 1 us for nosine or pointing the cop, or for causing a firm Wind at the point thereof, is very simple and completely automatic.

The means devised by us for regulating the quadrant feed is intended to make this part of the machine automatic when once adjusted for any particular size of yarn, and the position of the quadrant-nut on the quadrant is l govern ed automatically by the pressure of the yarn upon the faller-Wire.

The following is a description of such parts `of the mechanism of the mule and the operation thereof as may be necessary to enable our invention to be understood, reference being made to the accompanying drawings.

Figures l and l* together represent in plan view the head-stock and main operating parts of a lnule containing our improvements, together with the center part of the carriage, much of the latter being omitted to save space upon the drawings, and in sai'd figures the spindles are omitted. Figs. i and 2 show a left-hand side elevation of the head-stock with the carriage in section, the wheels at one end of the carriage being shown as on the usual track. Fig. 3 is a rear elevation of the head-stock with the drawing-in friction in section.I Figs. 4t and 4 show a right-hand side elevation of the head-stoekwith the carriage in section; Fig. 5, a partial front elevation of the head-stock, the scroll-drum and its shaft being omitted.

Fig. 15 is a detail showing the drawingin drum and some offits cooperating parts. Figs. 1G and 17 are details showing parts of clutch and cooperating devices whereby the drawing-rolls may be made to start with or a little later than the carriage, the object in the latter case being to take out snarls before the rolls begin to deliver yarn. Fig. 18 is a detail to be referred to. it showing a clutch for drawing out the carriage. Figs. 19 and 2O show a modification of our invention to be described. Fig. 2l shows part of the shaft H7 and devices carried by it. Fig. 22 is a right-hand side elevation of the ratchet and flanged plate and cooperating parts of Fig. 21. Fig. 23 is a longitudinal section of the parts shown iu Fig. .21. Fig. 24 shows sepa- Yrately the forked or crotched stud, between the ends of which is inserted the clamp-spring t7. Fig. 25 shows part of the arm c3 and the upper end of the lever c4 separated, and Fig. 26 shows the upper end of the lever c".

Preparatory to describing with particularity the construction and operation of the parts we will state that the frame or head-stock 7, the carriage B, its spindle-driving drum 11S, the spindles K4, the faller K3, the counterfallerK?, the drawing-rolls K', the main shaft A,'the pulley A, loose thereon, the pulley AX, fast thereon and one side of which is concaved to receive a conical face of thc backoif friction wheel D, having an attached gear 32, the twist-pulley D, shown as fast on the main driving-shaft, the back shaft C622, the quadrant-lever F, the quadrant-screw K5 therein, the nut II thereon, the quadrant-segment Fw, and its drivin g-gear F9 are and may be all substantially as common in other wellknown forms of mules, the said carriage in practice having suitable wheels 102 w3, two only of which are shown in Fig. 2, to run upon suitable tracks 1124 in the backward and forward mot-ion of the carriage, all in usual manner.

We will first refer in our description more particularly to the parts instrumental in moving the carriage in its outward direction.

The main shaft A receives its motion from a belt extended around the pulley AX, said belt being driven from a suitable countershaft.

The shaft A has near one end a bevel-gear u?, that engages a bevel-gear a3 on a shaft a4, substantially at right angles to the main shaft. The shaft c4 has a gear a5, (see Fi g. 2,) which engages a gear a, running loosely on a stud 2, said gear a having fastened to it what is called a change-twist gear a7, the latter engaging a clutch-gear as, loose on a shaft a, said shaft being in line with and cooperatively connected to and so as to rotate the front roll 7c of the set of drawing-rolls.

The clutch-gear as serves as an intermediate gearin the drawing-out and spinning motion and effects the rotation of the drawing-rolls when it is in engagement with the clutch am, feather-keyed on the'shaft d.

The clutch-gear as engages a gear a on a short shaft am, the opposite end of which outside the head-stock has fast upon it a gear als, the latter gear engaging an intermediate gear. @14, which latter in turn engages a gear a, secured to a shaft c1, having loose on it a clutch-gear a, cooperating with which is a sliding carriage-clutch als, feather-splined upon the shaft am.

The clutch-gear a and the clutch als are shown separately in Fig. 1S, and partially in Figs. 1 and 2, by breaking out some of the frame.

The clutch-gear an, through two intermediate gears al and d20, engages and rotates gear (L21, fast on the back shaft @22, the rotation of the latter shaft being effective in giving outward motion to the carriage, as will be described.

The back shaft @Q2-in practice has a number of sprocket-wheels, as b', fast thereon, about which will be extended the metallic Hexible connections b2, represented as sprocketchains, the said connections being united to the carriage, as herein represen ted, in a yielding manner by or through connecting-rods h, having cooperating with them spiral or other springs b4. The rods referred to pass through holes in suitable bearing-stands 3, and the said rods lie sul'istantially vertically over the chains, the ends of the rods being represented as pivoted to large links 1225 of each chain.

The springs D* referred to enable the carriage to be started easily, as will be obvious, when commencing its inward run, and the springs will bear at such time against the stands 3, nuts 4t on the rods limiting the elasticity of the spring, other nuts, 5, (shown in Fig. 2,) limiting the movement of the rods during the outward run of the carriage.

The outward motion of the carriage B is stopped preparatory to backing off and making the proper changes for running in and winding on by mechanism now to be de- IOO IZO

scribed, viz: The back shaft L22 has fast on it a gear b5, (see Fig.` 4,) said gear engaging a gear b, secured to a shaft 197, having attached to it a suitable chain or sprocket wheel bs, about which is extended a chain b9, the latter going to and about the sprocket or chain wheel blo, secured to the shaft Z911, supported in suitable stands (i, bolted to the iioor having the track upon which the carriage runs. The shaft b has fast upon it, near its other end, a lever bw, (see Fig. 7 on the hub of which is hung loosely a lever 13, provided at one side with a projection 613x, the latter lever shown by dotted lines, Fig. 4, and free to move thereon, being connected with along rod b1, (see Figs. 4 and 5,) said rod being extended in the direction of the outward run of the carriage and being connected loosely with a swinging lever 515, pivoted at 7 on a stand 8. of the head-stock, (see Figs. 1n and 2%) said lever 1915 having connected to it between its ends by a stud-screw 100X a rod b1, connected loosely at its opposite end by a swivel-stud 0010 (see Figs. 9 and 11) with the clutch-lever Z917, the said rod at its end at a point beyond the swivel-stud havingapplied to it check-nuts 9, which in the movement of the rod to the right, viewing Fig. 9, as will be hereinafter described, will m eet the swivel-1 studand turn the clutch-lever D17.

The rod bw carries a dog Z918, to whichis connected one end of a spring Z219, the oppositel end of `said spring beingconnected to the, lower end of a lever Z920, (shown in Fig. 9 and? separately in Figs. 12 and 12 and partially: by dotted lines in Fig. 2,) said lever 520 beingl pivoted on a stud 12, supported in a suitable bracket (not shown) fixed to the head-stock,

and having at its inner end at one side a projection 13, which normally rests against the lower end of a curved or inclined flange 14 `(see dotted lines, Fig. 9) at the inner side of the oscillating change-lever b21, mounted on a stud 15, (see Fig. 5,) the normal strength of the spring Z919 being sufficient to maintain the lever Z220 in contact with said iiange. In this condition of the parts `the end 24 of the locking and adjusting lever Z923, also pivoted on the stud 12, rests against a shoulder 25 at the inner side of the said change-lever.

The locking and adjusting lever is forked at its lower end, (see Fig. 10,) and the forks are offset or set out of line, and each fork has in its end an adj usting device, as Q60, said adjusting devices contacting with a lever (222, (see Figs. 9 and 18,) said lever being that which engages and at proper times moves the carriage-clutch als to run the carriage out.

The lever Z217 in its normal posilion stands near the lever Z922. (See Fig. 18.)

The drawing-roll clutch-gear am is kept in engagement with the drawingroll clutch-gear a8 by the springr, (seeFig.16,) to be described, and during the outward run of the carriage and spinning, when the rolls are to rotate, the clutch-levert17 stands with its upperend(see Fig. 13) against the adjusting screw or de'- vice 11S of the drawing-roll clutch-lever b1", and the disengagement of said clutch from said clutch-gear is effected as the carriage completes its outward run by the lever Z917, acted upon by the rod Z916, as will be described.

As the carriage completes its outward run the shaft Z111 is turned far enough by the chain b9 to bring the arm Z112, fast on it, against the projection 513x of the loose lever Z913, before described, and cause said lever to be moved about the shaft bu far enough to move the rod bm to the left, viewing Figs. 4n and 4, causing it to push before it the lever Z915, (see Figs. 5 and 2%) thus drawing the rod Z116 to the right, Figs. 8, 2, and 9, causing the spring Z219 to be strained, the straining of the spring being continued until the set-nuts 9 meet the swivel at the lower end of the lever b", to thus move it and cause said lever to act against the carriage clutch-lever Z122 (shown in plan, Fig. 18) and move said clutch-lever far enough to disengage the clutch als and stop the said carriage, it having arrived at the outer end of its stretch, and at the same time said lever D22, owing to its contact with the locking .andadjusting lever Z223, moves the latter lever far enough to remove its end 24 from the projection 25 of the change-lever, thus unlocking said change-lever and leaving it free to be oscillated by the lever Z920, whose end is pressed against the inclined iiange 14 of said oscillating change-lever b21 lby the said spring 619 to move the upper end of said change-leverto the right, viewing Fig. 5. The

movement of the rod IfLG to the right, as described, moves the clutch-lever b, and its upper end (see Fig. 13) meets the adjusting device or screw in the upper end of the horizontally *placed drawing roller clutch f lever Z914 and moves it, as before described, to release the clutch from the clutch-gear and stop the rotation of the drawing-rolls.

From the foregoing it will be understood that `the lever Z913, (see Figs. 4a and 7,) hung loosely on lever Z212 and connected tothe carriage and drawing-roll clutches als and d10 through the rods 191,44 b1 and levers Z915 b, draws the said clutches out of engagement and stops the motion of the carriages and drawing-rolls at the end of the outward stretch of the carriage, and that the saidy clutches are held out of engagement through the action of the change-lever b21 until the backing-off anc winding-on and taking-in motions are completed, said clutches thereafter again coming into engagement, but not until the oscillating change-lever b21 has made its change at the beam or at the end of the inwardrun of the carriage preparatory to repeating the operation of drawing out and spinning. i

The belt-shipper ci, mounted toturn on `a pivot 101, has a flattened hub 100, and projecting upwardly from said hub it has an arm 102, and the upper end of the belt-shipper has extending rearwardly from it two proj ections 1,20.

IOO

IIO

IZO

The belt-controller chas a forked or rockershaped foot which rests loosely on the flattened hub 100 of the belt-shipper c, and it is kept seated on said hub by means of a spring 103, connected to the said controller and to the arm 102. l

The change-lever l)g1 has a cam-shaped groove 17, (shown in Fig. 13 by full lines and by dotted lines in Fig. 9,) said groove receiving one end of a bell-crank lever c', (see Fig. 14,) provided with a jointed link c2, adjustably connected by a bolt 18 (see Fig. with an arm c3, forked at its outer end and provided at its under side between its ends with two lugs 10%, said lugs embracing the projections 1520 of the shipper-lever.

)Vlien the carriage is moving inwardly and winding the yarn on the spindles, the beltcontroller c holds the belt on the loose pulley A, the spindles being then rotated by the taking in of the carriage, but just before the carriage yarrives at the roller-beam, when the winding-on motion of the spindles is to be stopped, the belt-controller is, through the rod c, common to mules, pushed to the left far enough to put the belt onto the fast pulley to start the spindles, so that as the guiding-faller rises the yarn will go to the tops of the spindles without snarls, and immediately thereafter the said change-lever is moved and the carriage is started out with the spindles at speed. As the change-lever is moved at the completion of the inward run of the carriage toward the roller-beam, it, through the arm c3, moves the belt-shipper and causes its flattened hub, embraced by the rockershaped foot, to act on the belt-controller to maintain it in position to keep the belt on the fast pulley while the carriage runs out for spinning.

The back-off friction l), before referred to, has (see Fig. 1) an annularly-grooved hub D90, in which enters a roller or other stud D91, (see Fig. 3,) carried by a lever @20, pivoted at 18X, said lever at its outer end having a vertical slot which receives a pin 1f), made adjustable in a slot at the upper end of a lever e, pivoted at 20, the lower end of said lever having jointed to it a rod 21, to be hereinafter described. The lever @20 is extended through a slot' in the end of the arm c3, and said lever acts against said arm as the carriage completes its outward run, as shown in Fig. 2, and holds the back-off friction from contact with the fast pulleyA until it is time for the backing off to commence, but the arm c3 is not then moved, for it is held by the chan ge-lever.

During the latter part of the outward run of the carriage the belt-controller is gradually removed from the fast to the loose pulley by or through the rod cl2, before referred to and common to mules, for a distanee sufficient to reduce the speed or momentum of the spinvdles preparatory to backing off, and after the carriage completes its outward stretch and the change-lever b21 is moved to the right and the belt-shipper c4, moved by it through the arm c3, again effects a change of position of the flattened hub 100, which acts on the beltcontroller to keep it in position to maintain the belt on the loose pulley during backing off and the running in of the carriage to the beam. As the arm is moved to the right by the change-lever it permits the lever @20 to follow it and put the back-off friction D into clutch with the fast pulley mounted on the shaft A', having the grooved pulley D',which, through suitable band, rotates the spindles for spinning.

The back-off friction, mounted loosely on the shaft A', is always rotated, but in a direction opposite that in which the fast pulley turns during spinning, and when lthe back-off friction is permitted to engage the said fast pulley the-backoif friction thereafter acts to turn the shaft A to unwind the yarn from the point of the spindle preparatory to winding on.

The lever c2@ is moved to put the back-off friction intogear by the following devices, viz: a lever e, pivoted at 20 and connected by stud 19 in lever e2, entering a slot in lever @17, the lever el7 having connected to it a rod 21, (see Fig. 2,) extended (see Fig. 2a) to the outer end of the frame, where said rod is guided in a swivel-stud 105 and surrounded by a spring 21X, acted upon by a lever 10G, having a slot 107, in which will be secured a roller or other stud adapted to be struck by a lever pivoted on the carriage and suitably connected in usual manner with the guidingfaller, the said lever meeting the said roller or other stud when the carriage is going out, thus turning the lever 106, causing it to cmpress the spring 21 and store up sufficient power to move the levers e and e2@ to put the back-off friction in gear, the shipper and auxiliary levers c and c4 having been previously moved, as stated. After the backing off has been completed the back-off clutch will be thrown out of gear, as will be hereinafter described, and the carriage will be run in and the spindles be rotated in the direction to wind the yarn thereon, and this done the carriageclutch als and roller-clutch ctw are again engaged and the carriage is again started outwardly.

The change-lever b21 having been moved by the lever 1120, as hereinbefore described, said change-lever in its new position, it being the reverse of that shown in Fig. 5, causes the belt-shifter to move the belt onto the loose pulley A and keep the'carriage and drawingroll clutches as and d10 out of engagement, leaving the mule free to back off and wind on as it runs in toward the beam.

The locking and adjusting lever Z323 holds the carriage-clutch als out of engagement during the backing-off and winding-on operations, and at the same time the drawing-roll clutch am is held out of operation and the rolls are left at rest, and this same lever Z923 by its lug 24 engaging a projection 25 of the oscillating lever Z921 locks the latter in place While the carriage is running out and spinning.

The oscillating change-lever b21 is reversed at the end of the inward run of the carriage by means of a lever c6, (see Figs. 2 and 5,) hung on a stud 26, said lever at its opposite end being pin-jointed to a vertical rod c7, (see Fig. 5,) normally elevated by a spiral or other spring o8, seated on a swivel-collar 28, swiveled in `the lever b21, the upper end of said spring acting against the collar cg, made adjustable on the rod cT by a suitable setscrew 27.

The lever Z121 is held in theposition for winding,or in what is sometimes called its takingin7 position, by a hook 010, (see Fig. 5,) said hook being lifted to disengage said lever asV the carriage arrives at the end of its inward run by an inclined plate c, mounted on the carriage.

The lever b21 at its rear side'has a stop-lug 107, which contacts at the extremes of its throw with a suitable bilder attached to the head-stock, one of said buffers being shown at 108, Fig. 5.

As the carriage approaches the usual rollerbeam T (see Fig. 8) in its inward run the usual faller-rod 29 acts on and depresses the lever c, pulls down rod c7, and compresses the spring cs, so that when the said lever b21 is released by raising the hook C10 the said spring will quickly act to throw the said lever into the position shown in Fig. 5, which is the position it occupies during the outward run` of the carriage, such movement of the lever Ab21 effecting the engagement of the clutches als and d10 and the shifting of the driving-belt onto the fast pulley.

)Vhen it is desired to rotate the spindles backwardly for what is called backing-off,

` the faller-wire K3 being at the same time depressed to be ready for the Winding-on, the backing-off friction device D is moved laterally by the lever @20, so Aas to engage the friction side of the fast pulley A on shaft A in order that the said friction-pulley D for the instant by its engagement with the said pulley AX will rotate the main shaft in a reverse direction and with it the twist-pulley D' for a suflicient length of time to effect a reverse rotation of the spindles and the consequent backing off of the yarn. The twist-pulley D receives upon it the cylinder-driving band, (not shown,) said band in practice passing over said pulley in one groove thereof and then over suitable carrier-pulleys about the cylinder-pulley and back again over the twistpulleyin the other groove thereof, all as usual in mules, so said band need not be herein further illustrated.

The power for running in the carriage is applied to the pulley E, the shaft on which it is secured having a bevel-gear e2, which engages a bevel-gear e3 on a vertical shaft e4, having splined on it the concaved half c5 of the so-called winding-on and drawingin friction-clutch device, the other half, e6,

being loose on the said shaft @land being provided With a bevel-gear e7, which engages a bevel-gear es, loose on the back shaft @22, but fast on one end of the hub of the scroll-pulley e9. This scroll-pulley receives about it a flexible 'metallic connectionelo, shown as a chain, one end of the said chain being made fast to the said scroll7 while its other end is made fast to a taking-in drum en, said drum having a gear 612, which, in engagement with the intermediate gear el?, rotates the back shaft during the running in of the carriage. The drum en, the shape of whichis best shown in detail, Fig. l5, has near one end acam-like or eccentric projection 33X, which during the latter part of the running in of the carriage receives upon it the chain @10, thus diminishing the speed of the carriage as it approaches the roller-beam more than is possible by means of the scroll-pulley alone.

The part ci of the friction device is put out of engagement with the part e6 While the carriage is running out by means of a lever @14, which rests against the under side of the lever @15, pivoted at el, (see Fig. 5,) it having (see Figs. 2, 3, and 5) a projecting arm tu', forked at one end and embracing pins 102x, extended from the opposite sides of a loose collar 103x, loosely connected with the hub of the clutch part e5, the lever @15, after it has been moved to separate the said clutch parts, said lever @l5 being held in such position bya lug 34, extended from the `so-called upright back-off7 lever e1T (see Fig. 3) and acting on said lever. (See Fig. 3.)

The lever @14 has its pivot at 5G, and it has a hub which enters a hole in the opening-1ever e19 of the taking-in friction, said lever .e14 (see Fig. 2) also having an arm provided with a set-bolt 35, which enters a slot w12 (see Fig. 2) in the lever e, said boltserving to hold the said lever c14 inthe position it may have been put by the adj usting-screw @18, carried by the lever e and abutting against the said opening-lever eli. The right-hand end (see Figs.` 2 and 5) of the opening-lever @19 rests against the part 37 of the oscillating changelever b21, (see Fig. 5,) while the carriage is running out and until the position of said lever is changed at the end of the stretch preparatory to running the carriage in, when the said oscillating change-lever b21 is moved,` as stated, to its taking-in side, leaving the lever el free to move and let the friction part e5 drop into engagement with the part e, but this engagement is not effected until the backing off is completed, for during the backing oii' the lug 34 on the lever e" bears on the end of lever 915, but as soon as the backing-olf operation is completed the lever @17 in its movement, as before described, opens the backingoff friction and removes the lug 3l from the lever 615, letting a spring 40 act to quickly engage the taking-in friction.

The quadrant F to regulate the winding on, as in otherA mules, is driven by a rope F', adjustably secured at one end to the carriage IOO IIC

B by an adjustable fastening F2 on a stand F3, said rope passing over a carrier-pulley F1 at the rear of the head-stock and then back toward the quadrant, where it is secured to the scroll-drum F5, fast on a shaft Fl". Another rope F'T is made fast to the carriage by a like fastening FS and is wound around th-e said scroll-drum F5 in the opposite direction and secured thereto.

The shaft FG has secured to its end a gear F, which engages the teeth of the segmental part F10, suitably bolted or attached to the quadrant-frame F, so that as the carriage is moved to and from the roller-beam T motion is conveyed to the quadrant by the described ropes and gears.

The usual sliding nut H of the quadrantframe F is connected loosely with the winding-chain H3 by the winding-chain fastenings H and H2, said chain being secured at one end to the chain-drum H1 of the carriage B, said drum having a gear H5, which engages and rotates a gear Il, fast on the cylindershaft H7, provided with the usual tin cylinders H8, the motion of which through cotton bands (see Fig. S) drives the spindles K1 in usual manner.

The motion of the spindles K1 for winding on is obtained while the carriage B is moving away from the sliding nut vH of the quadrant at a speed greater than the speed of the nut itself, the gain of the carriage over the chain or sliding,` nut revolving the windingdrum H1 and through the gears H5 and H6 turning the usual cylinders H8, thus giving motion to the spindles in the usual way. In the first wind which is made on the bare spindle the quadrant sliding nut H will start at a point near the bottom of the quadrantframe F, and the speed of the spindles will be increased very slightly as the carriage B is moved to the beam T. At the next wind the speed of the spindle should be diminished at the beginning of the wind in proportion ras the yarn wound on in the previous wind increased the diameter on which the winding is now to be effected. It will therefore be understood that the quadrant sliding nut H must be raised enough to give the proper spindle speed to wind on after each successive draw, the spindle speed being diminished in suitable proportions at the beginning of each winding on until the cone has been formed, after which the winding-011 motion is approximately uniform until the full cop is formed. As the yarn K is being wound on it passes from the drawing-rolls K over the tension-wire of the counter-:faller K2 and under the guide or faller wire K3 to the spindle K1, and when the spindle speed is too great for the amount of yarn to be taken up the sliding nut H is raised by means of the quadrant-screw K5, at the lower end of which is the usual bevel-gear K6, (see dotted lines, Fig. 5,) which engages a bevel-gear K7 on a short shaft KS, passing through the journal of the quadrant-frame, the said shaft having G Maceo secured to it a grooved wheel K', connected by means of a band K10, of preferably round leather, with two grooved wheels K11 K12, mounted loosely on studs made fast to a stand K13, suitably bolted to the carriage B. Secured to grooved wheel K12 is a stop-wheel K11', (shown separately in Fig. (3 and by dotted lines, Fig. 4,) above which is hung a stop-lever K1", pivoted on a stud 42 of the carriage.

The carriage has bolted to it a stand m', (see Figs. l and 4,) which receives a rack K1", which is free to slide in said stand when not held in place by the pawl m2. This rack has connected to it at its lower end a small chain K1, which is passed through an opening in a lever K15, and thence through an opening in a finger K18, secured to the counter or tension faller-rod K11), said chain passing around the faller-rod 29 and being secured to an adj usting-screw K21 on a finger K22, which is secured to the said faller-rod.

If the spindle speed becomes too great while winding on, the strain of the yarn will draw the counter or tension faller-wire K2 down, thus dropping the stop-lever K15 into engagement with stop-wheel K11, and, holding said wheel fast, will cause the carriage in its motion to turn the feed or grooved wheel K0 and through bevel-gears K6 K1' and screw K5 move the sliding nut H upon the quadrantscrew until the spindle speed is diminished sufficiently to allow the counter or tension faller K2 to resume its proper level, when the said stop-lever will be raised from engagement with the said stop-wheel K11. This done the quadrant-screw will stop its rotation until the spindle speed again becomes too great for the cone of yarn which is being wound from draw to draw.

The device for diminishing the quadrant feed as the cone is being formed consists of a nut m, having (see Figs. l and 5) a camshaped wing, said nut being mounted on the threaded shaft K8 and being adjusted thereon to complete its stroke toward the wheel K9 simultaneously with the completion of the conical base of the cop.

The vertical rack K17 has loosely connected to it a lever m3, pivoted on stand mx, bolted to the front of the carriage B, and on said lever is an adjusting device m5, the said rack being raised in its guide bythe contact of said adjusting device with the wing of the nut m as the carriage is moved out, said nut being moved on said shaft intermittingly from draw to draw. The feed of the nut m is diminished as the vertical rack K17 is raised and as the cone is formed, and the cone having been formed the motion of the nuts m and H ceases. After the formation of the cone referred to the builder-motion assumes cont-rol of the faller and counter-faller and actu ates them in usual manner, except as hereinafter described when referring to our improved nosing-motions.

The pointing or winding firmly of the nose of the cop is accomplished by means of a rack' IOO IIO

i side of the spline.

n, free to slide in a groove in the quadrantframe F, it having cooperating with it a pawl n', said rack having attached to it a nosingchain n2, which is passed under the quadrant-frame F, and a lever n3, pivoted at 44, said chain being made fast to the windingchain fastening' H2. As the carriage B is moved toward the beam T and the quadrant is turned down in a forward direction the arm n4, carried by the quadrant, strikes the lever 'n3 and presses it onto the nosing-chain, and thus causes it to impart an extra amount of lnotion to the winding-on chain H3, and thus increase at the inward run of the carriage toward the beam the speed of the spindles, to thus wind the yarn more tightly onto the bare part of the spindle or for finishing the nosing of the cop.

The device for moving the nosing-rack n up to shorten the nosing-chain n2 as the cop is being built, as is required in all mules owing to the decreasing diameter of the spindle toward its top, consists of a vertical shaft ni, having a step 45, (see Fig. 4,) resting on a Cain-shaped lever nfgsecured to a nosing-shaft 027, having at its other end a lever n, (see Figs. 5 and 6,) connected through the rod n10 with the cop-building former n, of usual shape. )Vhen the conical base of the cop has been built, the building-former nf comes into position to move the lever n3 and thus gradually raise the shaft a5. As the quadrant is moved out at the end of t-he stretch the adjusting-screw nu, connected to the nosingrack n, strikes the cap '2112 of the vertical shaft 'a5 and raises the nosing-rack n a little, and it is held in its lifted position by a pawl fn. During the operation of building the cop the building-former ni is moved progressively to- Ward the roller-beam.

To start the drawing-rolls at the proper time in relation to the motion of carriage B from the roller-beam T, the drawing-roll clutch am has a wide space made in it, as shown in Fig. 16. `The shaft a9 of the front drawing-rolls has a spiral spring r3, one end of which is connected to a collar ri, fast on the shaft a, by a set-screw 47, the other end of the spring` being' inserted in the clutch 0,10, the latter having a splineway 4S, (see Fig. 17,) wider than the spline 49, by means of which the clutch is enabled to rotate the said shaft, said spring normally acting to keep the clutch d10 and clutch-gear d8 in engagement. The hub of the clutch is surrounded by a ring i", adjustably attached thereto by a set-screw r2, said ring having a pill 1", which is extended into the splineway 47 far enough to engage one This ring may be adjusted on the clutch so that the working or righthand side 50 of the splineway (see Fig. 17) maybe set at any desired point with relation to the spline when the clutch is not engaged, thus permitting the clutch to rotate more or less, as may be desired, before imparting inotion to the front-roller shaft a9. Thus by means of the ring-clamp 1, with pin 9"' to stop the clutch am and adjusted with set-screw r2 in ring r, the drawing-rolls K can be arranged to start with or a little later than carriage B, which arrangement renders it possible to take out snarls before the drawing-rolls begin to deliver yarn.

The loc-king and adjusting lever 1923 has its lower end forked (see Fig. 10) and provided with adj usting-screwsao, the heads of which act on the lever Z222, and by adjusting these screws just the desired extent of motion `may be imparted to the clutch als at just the desired time with relation to the motion of the carriage.

Referring to Figs. 19 and 20, we have shown a modification wherein the shaft al is provided with a sprocket-wheel 200, which drives a chain 201, extended about a sprocket-wheel 202 on the back shaft @22, and we have shown the back shaft as having a secured sprocketwheel 203, which by a secured sprocketchain 204 on a sprocket-Wheel 205, supposed to bc fast on the shaft of the drum e, rotates the said drum. These two chains and sprocketwheels are mechanical equivalents for the gearing previously described as operative between the shaft al, back shaft, and drumshaft, and this invention is not limited to the exact construction shown of the devices for positively connecting the three shafts-viz., the shaft am, back shaft, and j drum-shaft. The cylinder-shaft H7 has fast on it a ratchet- Wheel 5. Alongside of this ratchet-Wheel and loose on said shaft is a gear H6, having a flanged plate t3, provided with a stud t2, on`

which is pivoted a pawl t. This pawl has a wing s, having mounted loosely on it a forked stud s', which is engaged by one end of an engaging device t7, shown as a spring-like clasp faced with leather and partially surrounding a clasp-holder ti, free to turn on the said cylinder-shaft inside said clasp, the said clasp-holder having an extended arm, which rests on a lever tw, pivoted at t on the carriage, the short arm of the said lever normally resting on a rest t5, also connected to the carriage. A spring t, connected to the arm of said holder t4, keeps it against the rest t5. W'hilethe carriage is running out the arm of the holder if* lies on the short arm of the lever 10, supported by a suitable rest t5; but the pawl t is not at such time in engagement with the ratchet-wheel 5, because said pawl during such operation is held up, due to the fact that the plate 153, carrying the said pawl, is traveling backwardlywith relation to the teeth of the ratchet-wheel in the direction of the arrow, Fig. 22, and at such time the plate t3, carrying the pawl t', causes said pawl to drag the engaging device about the hub of the` holder t4, and consequently the point of the pawl t' is lifted from contact with the ratchetwheel 5, and the said pawl is held from the said ratchet until completion of the backing off. The gear H6 and plate t3, carrying the said pawl during the running out of the carriage and spinning, are moved in the direc- IIO tion of the arrow w3 in Figs. 4 and 22, but the ratchet-wheel 5, fast on the cylinder-shaft, is moving in the opposite direction at a faster speed, the faster speed preventing the pawl from catching into a tooth of the ratchet; but the movement of said ratchet is reversed while the backing off is taking place, but without engaging the pawl. The pawl '1f' is to engage said ratchet immediately after backing olf, so as to be in position before the earriage starts to wind on, and during winding on the said ratchet is moved at a slower speed, due to the movement of the quadrant. To do this, the lever eu near its lower end has connected to it the bent end of a rod 300, (see Fig. 2,) extended back to and through a projecting eye SOI at one side of the lever D15, said eye merely acting as a support to sustain the free end of said rod in its slight movement, and said rod has upon it a projection 12, (see Fig. 4,) the projection being so adjusted on said rod that just before the carriage completes its outward run the lower end of the said lever fm, extended below the carriage, meet-s said projection i12, thus moving said lever tw and causing it to lift the arm of the holder it, causing its hub to turn in the clasp, the direction of movement of the holder tending to yet keep the pawl out of engagement with the ratchet; but such movement of the holder in the clasp so places the holder that any sudden downward movement of its arm will act to quickly move with it the clasp in a direction to quickly throw the pawl if into engagement with the ratchetwheel. Af ter the backing off has been accomplished the winding on must commence, and to effect this the taking-in friction parts c5 c6, before out of Contact, must be put in contact. As the friction part c5 drops after backing off, as has been described, to comm ence the drawing in of the carriage and the winding of the yarn on the spindle the lever e171 is turned, as before stated, causing the rod 300, connected to it, to be moved with it far enough to cause the projection l2 to leave the lever tw, letting` the spring t, connected to the holder, act, it turning the clasp 't7 in the direction to cause it to quickly turn the pawl t down, so as to engage the ratchet-wheel 5, and as soon as the pawl engages said ratchet-wheel, the plate t* and the friction part having `also beenl engaged, the motion of the ratchet-wheel is reversed by the pawl as the inward motion of the carriage is begun, and the cylinder is turned to wind on the yarn. At the completion of the winding on the shaft Il7 is given a faster speed, as common to mules, and the teeth return from effective engagement with said pawl, and the usual changes which take place at the inward run of the carriage are effected. The plate 't3 is moved in a direction opposite the arrow when the carriage is moving out or spinning and while winding on at the inward run.
